Novel grinding part and automatic grinding device

Abstract

The invention provides a novel grinding part. The grinding part is of a cylindrical structure, a abrasive particle layer, a flexible base material layer and a hollow shaft structure are sequentially arranged from outside to inside, the abrasive particle layer is arranged on the flexible base material layer, the hollow shaft structure is wrapped by the flexible base material layer, and the grindingpart is arranged on the corresponding grinding device through the hollow shaft structure. According to the grinding part, the cylindrical side surface serves as a grinding contact surface, so that the linear speed of abrasive grains during grinding is relatively consistent, and the abrasive grain layer is in matched contact with the curved surface of a product to be machined through the flexiblebase material layer, so that uniform grinding is realized, and the grinding effect is ideal. The invention further provides the automatic grinding device. The grinding device comprises a machine frame, a power part and the grinding part, wherein the power part and the grinding part are installed on the machine frame, the power part is in driving connection with the grinding part so that the grinding part can rotate at the set rotating speed, cleaning cooling water can be applied to one side of the grinding part, the surface temperature of a ground workpiece is effectively reduced, and scraps are removed in time.

Description

technical field [0001] The invention relates to the technical field of grinding and processing, in particular to a novel grinding component and an automatic grinding device, which can be used for grinding the surrounding sides and R positions of the casings of 3C products such as mobile phones. Background technique [0002] With the rapid development of 3C product technology, the performance and appearance of 3C products are important factors that determine whether businesses can successfully seize the market. As one of the most popular electronic consumer products, mobile phones are updated at a high speed, and are gradually developing towards thinness and fashion. Consumers have increasingly stringent requirements for mobile phone accessories. The mobile phone case is one of the important accessories of the mobile phone. The surface photochemical treatment step is the key processing process of the mobile phone case, which directly affects the subsequent painting effect, wh...

The mobile phone shell is one of the important accessories of the mobile phone. The surface photochemical treatment step is the key processing procedure of the mobile phone shell, which directly affects the subsequent painting effect, and then affects the appearance of the mobile phone shell product

[0003] The surface photochemical treatment step in the production and processing of mobile phone shells involves grinding devices. At present, disc brushes are usually used to polish and polish the circular arc sides and four corner R positions of mobile phone shells, which has the disadvantage of low grinding and polishing efficiency.

In addition, the industry also uses five-axis machine tools for surface photochemical treatment of mobile phone casings. A disc is installed at the end of the five-axis machine tool, so that the end face of the disc is used for grinding and polishing, but the linear speed of the end face of the disc from the center of the circle to the outer circumference of the circle is From zero to the maximum value, due to the inconsistency of the line speed, the removal depth on the grinding surface is different. At the same time, when the cooling chip removal water is applied, the water is thrown out, so that the cooling water cannot effectively reach the grinding area, so that it cannot be effectively Reduce the temperature in the grinding area and remove debris in time, which will affect the smooth progress of industrialized production
